B细胞已成为一种重要的免疫细胞类型,可以靶向治疗多发性硬化症(MS)。用抗cd20抗体消耗B细胞可有效治疗多发性硬化症。然而,阻断B细胞活化因子(BAFF)和A增殖诱导配体(APRIL)这两种对B细胞发育和功能至关重要的细胞因子的atacicept治疗反而增加了多发性硬化症患者的疾病活跃性。一个接受者失败的原因尚不清楚。这些治疗在临床结果上的显著差异表明B细胞在多发性硬化症中具有炎症和抗炎功能。本文综述了B细胞在多发性硬化症中的重要性,讨论了不同的B细胞亚群发挥炎症和抗炎功能,以及治疗如何调节多发性硬化症患者的B细胞功能。此外,我们还讨论了BAFF和APRIL在多发性硬化症中的潜在抗炎功能。
B cells have emerged as an important immune cell type that can be targeted for therapy in multiple sclerosis (MS). Depleting B cells with anti-CD20 antibodies is effective in treating MS. Yet, atacicept treatment, which blocks B-cell Activating Factor (BAFF) and A Proliferation-Inducing Ligand (APRIL), two cytokines important for B cell development and function, paradoxically increases disease activity in MS patients. The reason behind the failure of atacicept is not well understood. The stark differences in clinical outcomes with these therapies demonstrate that B cells have both inflammatory and anti-inflammatory functions in MS. In this review, we summarize the importance of B cells in MS and discuss the different B cell subsets that perform inflammatory and anti-inflammatory functions and how therapies modulate B cell functions in MS patients. Additionally, we discuss the potential anti-inflammatory functions of BAFF and APRIL on MS disease.
